Referring in detail" to the dravvings,-. and for: the present; more particularly to- Figs. 1 and 2-;thereof5rdesi'gnatesa-base of suitable dimensio'ns,- preferably.- ofcast metal which; is provided in its uppersurfac'e? with a-cavity ordepressionfi of rectangular form having; raised outer edge port-ions: forming the rab'b'ets indicated at" 7 extending in parallel relation to-v the side and: end edges of said base. j The-surface of the "cavity or depression" 6. at? its approximate center isalso formed with spiaced" transversely: extending raised portions-0r ribs-8. a

A presserplate-9 isremployed incohjunc tion with the? base 5 and may be: operated by any convenient means, saidap-resser-head having a maximum-length and width-equal to the flength-and widthlof the depression 6 in. the-base at the inner sides-*of-the-frabbets 7, the bottom; face of the pre'ss'er head-1: having a narrow marginal ribior-rshoul-den 10 substantially; equal in thickness to :the depth of the depression 6-below the upper surface of the rabbet 7;.- Said :p-I'QSSEP headisi also centrally provided with the: relatively wide transversely;extending; rib -l1 h'a -ving:a width equal-tothe distance betweenthe spaced --ribs' 8fon+the base.- v

The :ca'rdvholdingaleaf oriinsertrconsistsrof a' sing'le sheet :of celluloid or similar flexible transparent.material ofvproper size'gwhichis suitably cut and folded upon; itself to propart-s vide opposed sections indicated at 12 which remain integrally connected with each other along one of their longitudinal edges, one of said sections being centrally provided with a I transversely extending slot 13 therein which is of uniform width while the other section is centrally provided with a wider slot having centrally curved portions indicated at 14 which are designed to facilitate entrance to the pockets formed between the opposed sections of the celluloid sheet.

A strip of linen or other flexible material 15 is first arranged upon the base 5 in the space between the ribs 8 thereon. The folded sheet of celluloid is then arranged in place and fits snugly in the depression or cavity 6 within the rabbet 7 and with the lower sec tion of the sheet of celluloid at opposite sides of the slot 13 therein extending over and upon the flexible strip 15. A rectangular binder strip 16 also of flexible material similar to the strip 15 is then arranged in position, said binder strip seating upon the surfaces of the rabbets 7 and being of suflicient width to project inwardly therefrom and over the marginal edges of the upper section of the celluloid sheet. The opposite longitudinal portions of this binder strip are integrally connected with each other by the central transversely extending web 17 of substantially the same width as the strip 15 and overlying the lower section of the celluloid sheet at opposite edges of the slot 13 therein and between the opposed edges of the slot in the upper section of said celluloid sheet. The presser head 9 is then brought downwardly under pressure upon the inwardly projecting portion of the flexible binder strip 16 and upon the web 17 thereof, the ribs 10 and 11 of said presser head firmly pressing the binder strip upon the celluloid sheet and also pressing the lower section of the celluloid sheet at opposite edges of the slot 13 upon the fabric strip'15. By any suitable means, the presser head 9 may be heated, or the base 5 may be heated to the required temperature so as to soften the celluloid sheet or render the same sufficiently plastic so that the fabric material will securely adhere thereto.

After the celluloid and the fabric parts have thus been adhesively connected with each other so that the celluloid sheet will be retained in definite relation to the edges of the binder strip 16, said parts are then removed from the base 5 and reversed in position so that the fabric strip 15 is uppermost and then placed upon the metal base member 18. To the opposite side and the end edges of this base member, the presser plates 19 are hingedly connected as at 19, said hinges being located adjacent the upper surface of the base and in parallel relation therewith. The presser plates are preferablyv provided with suitable finger pieces 20 insulated therefrom whereby said plates may be moved from the normal position seen in Fig. 4 of the drawings the celluloid and also over the ends of the transverse fabric strip 15. The base 18 and the plates 19 are also suitably heated so as to cause the inwardly folded marginal edges of the binder strips to securely adhere to the celluloid.

The connected parts are then removed from the base 18 and by means of a sewing machine, a line of stitching is run around the marginal edges, permanently securing the parts of the binder strip 16 on opposite sides of the celluloid to said celluloid sheets. Also similar lines of stitching may connect the fabric strip 15 adjacent its opposite edges to one section of the celluloid sheet at opposite edges of the slot 13 therein. In this manner, it will be apparent that the leaves or inserts each having two pockets with transparent side walls may be easily and quickly made. Such inserts are adapted to be secured in any desired number within an outer cover or holder, the fabric strips 15 and 17 of the several leaves being centrally stitched to said cover or holder.

From the foregoing description considered in connection with the accompanying drawings, it will be seen that I have devised a method and means for insuring the accurate and uniform production of such card holding devices, and in view of the simple nature of the apparatus required, it will be apparent that these operations can be executed at nominal cost and without requiring expert skill upon the part of the workman.

I have herein shown and described an embodiment of the apparatus which I have found to be entirely satisfactory in practical use. Nevertheless, it is to be understood that my new method and device for assembling the several parts of inserts for card cases, are susceptible of more or less modification in the form, construction and relative arrangement of the several parts thereof, and I therefore, reserve the privilege of incorporating the essential features thereof in all such alternative mechanical structures as may be fairly embodied within the spirit and scope of the invention as claimed.
